1 Unioeste Toledo, PR 2 IFPR  Foz do Iguaçu, PR 3 Unioeste  Toledo, PR (in memoriam) 4 Aluno de pós-graduação  Universidade Estadual de Maringá  UEM  Maringá, PR RESUMOAvaliaram-se os tempos de indução e recuperação de quinguios (Carassius auratus) expostos a dois anestésicos, eugenol e benzocaína. Foram utilizados 128 juvenis com peso médio de 2,07±0,53g e comprimento total médio de 5,51±0,56cm. A benzocaína mostrou ser mais eficiente do que o eugenol em relação ao tempo, tanto para indução ao coma quanto para a recuperação à fuga e também no que diz respeito à sobrevivência. As doses de benzocaína com melhores resultados foram de 87,5 e 100mg.L -1 . O eugenol proporcionou demora na indução e na recuperação dos animais, além de ter apresentado mortalidades quando as doses anestésicas foram elevadas. . The eugenol resulted in a delay of animal induction and recovery, and also presented mortalities when the anesthetics doses were increased.

The anaesthetic effect of camphor (Cinnamomum camphora), clove (Syzygium aromaticum) and mint (Mentha arvensis) essential oils on clown anemonefish,Amphiprion ocellaris(Cuvier 1830)

“…These doses did not cause mortality. The ideal clove oil concentration established in this study (equivalent to 28 mg L À1 ) is relatively close to that (50 mg L À1 ) found for kinguio (Carassius auratus) (Bittencourt et al 2012) and pacu (Piaractus mesopotamicus) (Gonc ßalves et al 2008) and is also similar (37.5 mg L À1 ) to fat snook (Centropomus parallelus) . This is also similar to the results found by Cunha and Rosa (2006), who defined 20 mg L À1 as the ideal concentration for ornamental sea fish.…”

“…The ideal clove oil concentration established in this study (equivalent to 28 mg L −1 ) is relatively close to that (50 mg L −1 ) found for kinguio ( Carassius auratus ) (Bittencourt et al . ) and pacu ( Piaractus mesopotamicus ) (Gonçalves et al . ) and is also similar (37.5 mg L −1 ) to fat snook ( Centropomus parallelus ) (Souza et al .…”

“…Several studies have shown the anaesthetic effectiveness of clove oil, which is composed of 70–90% eugenol, when used in freshwater (Inoue, Santos & Moraes ; Vidal et al . ; Oliveira, Carmo, Oliveira & Soares ; Simões & Gomes ) and marine fish that are intended for human consumption (Souza, Carvalho, Nunes, Scopel, Guarizi & Tsuzuki ) as well as in marine (Cunha & Rosa ) and freshwater ornamental species (Bittencourt, Souza, Boscolo, Rorato, Feiden & Neu ). Similarly, some recent studies have demonstrated the effectiveness of mint oil and its main component, menthol, for freshwater (Gonçalves, Santos, Fernandes & Takahashi ; Oliveira et al .…”

Clove oil as anesthetic for guppy

“…One possible explanation for this mortality may be due to the long-time of exposure of the animal to anesthesia in concentrations of 50 mg L -1 and 75 mg L -1 . BITTENCOURT et al (2012) have tested drug efficiency in kinguios (Carassius auratus) and observed a mortality of 25% of animals when exposed to concentration of 75 mg L -1 , besides presenting long recovery time. The concentration of 150 mg L -1 may have caused the mortality of animals due to a possible sensitivity of males at higher drug concentrations.…”
